Hello, we have this SW holster which does not go with any of our current arms, and thought there might be a SW collector out there who might be interested, but we don't know which model it was for. Anyone recognize it? Thank you!

My guess would be a model 39.

It's for a S&W Model 39 or 59, 4 1/2" or a Colt 4" Combat Commander.

Thank you all for your replies, I really appreciate it! We had made a tenatative guess of a model 39. Thank you again!
